Yup I agree it sounds like the libs. I had to install everything all over again on my A3000. When I put 3.1 on and tried to boot from the HD it would crash every time it started to boot. I forgot all about the libs for the 060. Once I put them in I stopped getting that same guru and all was okay. If you made an emergency disk from 3.9 it should have working 060 libs on it, but you never can tell.
